华北平原黄河宽V形河道控河机制分析
Analysis of River Control Mechanism of Wide V-Shaped Yellow River Channel in North China Plain
摘要
Abstract
The formation and evolution of the wide V-shaped channel of the Yellow River depends not only on the boundary form of the tec-tonic belt around the North China Plain and its interaction,but also on the remote response of the NE-trending extrusion of the Qinghai-Tibet Plateau.From Sanmenxia to the estuary of Bohai Bay,the Yellow River channel takes Lankao as the inflection point due to the control of the regional major faults on the riverbank,and the flow direction of the front and rear sections of the river channel changes from NEE to NE,forming a wide V-shaped channel combination style.The extension style of the river channel in the area is mainly manifested as long linear extension,followed by oblique array swing and short broken line turning.The Yellow River in the Sanmenxia-Zhengzhou section is produced in the fault depression zones surrounded by the southern Taihang Mountains tectonic belt and the Qinling tectonic belt.The piedmont faults have been strongly active since the Quaternary,and the main river sections are produced in the fault zone.The North China Plain is an irreg-ular hexagon-shaped depression plain on the plane bounded by four major tectonic belts.The long sides of the irregular hexagon are parallel to the Taihang Mountains tectonic belt and the Tai'an-Ji'nan tectonic belt,respectively.The main channel of the Yellow River is located in the hidden fault zone of Nanyang-Lankao-Pingyin-Kenli,with some of the NE trending long line tributaries parallel to and partially overlapping with the NE trending hidden fault zone in the area.The ancient diversion of the Yellow River in the verifiable historical period and the known abandoned Yellow River are all occurred in the hidden major fault zones.These hidden faults are the secondary faults of the two major tectonic belts along the river bank,and have mostly been significantly active since the Quaternary.The faults along the Yellow River and the hidden faults in the plain area are the main products of the formation and evolution of the orogenic belt,and also the main controlling factors for the generation,evolution,extension and turning of the river channels.关键词
